HUMIDIFYING DEVICE Filed Sept. 27, 1929 INVENTOR ATTORNEY Patented Dec. 9 1930 v UNITED STATES PATENT OFFICE CARL J. GUSTAFSON, F ABERDEEN, SOUTH DAKOTA HUMIDIFYING DEVICE Application filed September 27, 1929. fseriai nu sances.

' Another object of the invention consists of a conduit for conveying the moistened air to the engine carburetor.

More specifically stated a bafile arrangement is provided within the radiator neck connection to facilitate mixing of the moisture and air precedent to its introduction to the mixing chamber of the carburetor.

With the above and other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing 1 Figure l is a side elevationvof the present invention partly broken away to illustrate the construction thereof.

' Figure 2 is a horizontal sectional view taken on line 2-2 of Figure 1.

Figure 3 is av view similar to Figure 2 taken on line 33 of Figure 1.

Figure 4 is a vertical sectional View taken on line 4% of Figure 1.

Figure 5 is a detail sectional view taken on line 5-5 of Figure 1.

Referring to the drawing in detail wherein like characters of reference denote corre sponding parts, the reference character in dicates a form of housing to be seated upon the shoulder within the filling neck 11 of an engine radiator 12. The bottom wall of the housing is perforated after the manner of a false bottom 13 arranged in spaced relation thereto whereby the water within the radiator will be prevented from splashing within the housing. A cross bar or toggle link 14 horizontally disposed within the radiator 12 beneath the point of intersectionof the filling neck 11 therefor carries an upstanding shaft 15 projecting through the housing and a 010- sure cap 16 therefor. A thumb or wing nut 17 carried upon the uppermost projecting and tapped end of the shaft '15, is engageable with the outer and upper surface of the closure cap 16 to retain the latter inclosed position. Such arrangement, as referred to in the foregoing, will permit only water vapor to enter the housing .through'the respective bottoms. I

An airintake or breatherjpipe- 18 for a form of'air cleaner 19 will facilitate the discharge ofonly cleansed air through a pipe line 20 having communication with the interior of the housing 10. A'baffie plate 21 'bestshown in F igure 2 of the drawing carried by and depending the inner side wall of the housing across the discharge end of the: pipe line 20 will cause the cleansed air to be deflected downwardly upon the false bottom 13 and thence upwardly and over the upper inclined surface of the baflie plate to thoroughly mix the moisture andair whereby the air to be conveyed from the housing will be dampened or moistened for purposes to be better understood from the following de scrlption of the invention. A conduit 22,

carried by and having communication with the interior of the housing 10 above the baffle plate 21, is in turn joined to a form of conduit 23 through asleeve coupling 24. A valve member, designated as at 25, of annular formation and rotatably mounted between the component portions of the sleeve coupling 24;, is provided with an'opening' or orifice 26 designed for selective registration with an opening or air intake port 27 through the sleeve coupling in order that additional air may be introduced at this point to aid in'the introduction of a properly combustible fuel to the carburetor. A gooseneck or elbow fitting 28, arranged at a suitable point in the length ofthe'forin of conduit 23, includes a petcock or bleed valve 29 in order that excess condensation will be relieved after being retarded by bafile screens 30 disp0sed within the form of conduit 23 adjacent the connectionof the latter 1 with the engine carburetor;

V In actual tests with the'present invention, material saving in fuel was not-iced, reduction of carbon deposit and spark plugs were not fouled.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall Within the scope of the appended claim.

For instance, the housing '10 may be constructed Within the radiator when the radiator is manufactured, so as: to hide this member from view and not spoil the lines of the radiator.

Having thus described the invention, What is claimed is In a humidifying device for internal com bustion engines comprising a housing having a perforated bottom seated Within the filling neck of a 'rradiator therefor, a .false bottom of like construction arranged at spaced intervals to the housing bottom, air inlet and'discharge pipes having connection with the housing at spaced'hei-ghts, .a baffle plate carried by andobliquely disposed bep tween the connections of the pipes in ad- Vance of the inlet pipe tofacilitate mixing and dampening of the air with the water vapor collecting Within the housing, and means carried by the housing having'connection With the radiator to prevent displacement of the housing While in use.

In testimony whereof I aflix my signature.

CARL J. GUSTAFSON.
